| 摘 要： | 采用双剪统一强度理论（俞茂宏，1991）求出了矩形板的塑性极限荷载的统一解，得出了不同参数b值对极限荷载的影响曲线，从而得出了一系列从Tresca的单剪屈服准则解到双剪应力屈服准则（俞茂宏，1961）的矩形板极限荷载。文献中己有的Tresca解为本文的一个特例。将其用于混凝土矩形板的极限荷载计算，得出了满意的结果。双剪统一强度理论可以给出更符合于各种不同材料特性的合理解。

| Abstract: | This paper presents a new method to calculate the limit load of rectangular plate based on the Twin Shear Unified Strength Theory (M.H.Yu,1991). Unified solutions which consist of a series of solutions from the upper load limit based on Twin Shear Yield criterion (M.H.Yu,1961) to the lower load limit based on Tresca Yield criterion are obtained and solution based on Tresca Yield Criterion is a special case of the unified solutions. Influence of weighted parameter b on the limit load of rectangular plate is also proposed, which can be used to fit different properties of different materials. Using this new method to calculate the limit load of concrete rectangular plate, a satisfactory solution is gained. |
